Abstract: Fluid coupling assemblies and methods are discussed. The fluid coupling assemblies include a first coupling member, a second coupling member magnetically engageable with the first coupling member, and a seal member disposed between a portion of the first coupling member and a portion of the second coupling member. A magnetic engagement of the first coupling member and the second coupling member unseals a fluid flow path therebetween. In certain examples, the first coupling member is sealed by a valve member and the second coupling member includes an activation member. When engaged, the valve member is moved from a closed position to an open position by the activation member, thereby unsealing the fluid flow path. A magnetic force between the first coupling member and the second coupling member can be chosen such that the members disengage when a predetermined fluid flow path pressure is reached.

Abstract: An illumination optical unit for EUV projection lithography serves for obliquely illuminating an illumination field, in which an object field of a downstream imaging catoptric optical unit and a reflective object to be imaged can be arranged. A pupil generating device of the illumination optical unit is embodied so that an illumination pupil results, which brings about a dependency of an imaging telecentricity against a structure variable of the object to be imaged. This dependency is such that a dependency of the imaging telecentricity against the structure variable of the object to be imaged on account of interaction of the oblique illumination with structures of the object to be imaged is at least partly compensated for. An optical system for EUV projection lithography also has an imaging catoptric optical unit alongside an illumination optical unit and can additionally have a wavefront manipulation device.
